Modulating linear actuators, AC/DC 24 V, 450 N
Safety notes • The actuator is not allowed to be used outside the specified field of application, especially in aircraft or in any other airborne means of transport. • It may only be installed by suitably trained personnel. Any legal regulations or regulations issued by authorities must be observed during assembly. • The device may only be opened at the manufacturer‘s site. It does not contain any parts that can be replaced or repaired by the user. • The rotary supports and coupling pieces available as accessories must always be used if lateral forces are likely. In addition, the actuator must not be tightly bolted to the application. It must remain movable via the rotary support (refer to «Assembly notes»). • If the linear actuator is exposed to severely contaminated atmosphere, appropriate precautions must be taken on the system side. Excessive deposits of dust, soot etc. can prevent the gear rack from being extended and retracted correctly. • If not installed horizontally, the gear disengagement pushbutton may only be actuated when there is no pressure on the gear rod. • To calculate the actuating force required for air dampers and slide valves, the specifications supplied by the damper manufacturers concerning the surface, cross section, design, installation site and the air flow conditions must be observed. • If a rotary support and/or coupling piece is used, losses in the actuation force losses are to be expected. • The device contains electrical and electronic components and is not allowed to be disposed of as household refuse. All locally valid regulations and requirements must be observed.

Product features Mode of operation
Manual override High functional reliability
The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and moves to the position defined by the control signal. The measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators. Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked). The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.

Assembly notes Application without transverse forces
The linear actuator is screwed directly to the housing at three points. Afterwards, the head of the gear rod is fastened to the moving part of the ventilation application (e.g. damper or slide valve).
Application with transverse forces
The coupling piece with the internal thread (Z-KS1) is connected to the head of the gear rod. The rotary support (Z-DS1) is screwed to the ventilation application. Afterwards, the linear actuator is screwed to the previously mounted rotary support with the enclosed screw. Afterwards, the coupling piece, which is mounted to the head of the gear rod, is attached to the moving part of the ventilation application (e.g. damper or slide valve). The transverse forces can be compensated for to a certain limit with the rotary support and/or coupling piece. The maximum permissible swivel angle of the rotary support and coupling piece is 10° , laterally and upwards.
Caution
! If a rotary support and/or coupling piece is used, losses in the actuation force losses are to be expected. Stroke limitation
www.belimo.com
If the stroke limitations are used on the gear rod, the mechanical working range can be exploited from an extension length of 20 mm.
